India has numerous wild species and animals and tourist from all over the world comes to explore. India is vast country and divided into 5 regions namely north india, south india, east india, west india and central india each region has many states and these states have many wildlife parks and sanctuaries so each and every state open and closes these according to the rainy season like in south india rain starts in last may so national parks in that region during at time and in north india rainy season starts from last week of June so national parks closes according to that. These dates can be modified according to season also. Normally in India wildlife parks are closes from 15 May to October & open for tourist activity from November onwards till 15th May ( this one is peak season for wildlife tourist to India ). During rainy season it is very difficult to go for jungle safari. But during November to May one should choose national park according to visibility of animals, approach, density of wild species etc. If you keep these thing in mind you can visit more and more destinations with other theme as well like cultural, heritage, adventure etc. So plan according to that so that you can cover maximum destinations in your one visit to India.
